Woolly Mammoth
Not surprisingly, scientists have stumbled upon plenty of woolly mammoths that have been frozen in ice and largely preserved from when they were alive. Those scientists who are brave enough to explore areas in northern Alaska, Siberia, and anywhere around the Arctic Circle are the most likely to find one of these prehistoric creatures surrounded by a block of ice. In 2007, one of the most famous mammoths, a calf named Lyuba was discovered. Testing revealed she died nearly 42,000 years ago when she was barely one month old. Lyuba’s organs, eyes, blood, and skin were so well-preserved that some scientists believe it may be possible to clone her and potentially bring woolly mammoth’s back to life. That day isn’t here just yet, but if it does, we’ll owe it to the scientists who find these specimens stuck in ice.
